The isothermal oxidation of CoCr alloys in 760 Torr ...

The isothermal oxidation of CoCr alloys containing 030 Cr in 760 Torr oxygen at 1000 176 C has been studied kinetically and by appropriate physical techniques. Chromium additions to cobalt increase the parabolic oxidation rate to an almost constant level from 2 to 15 Cr while further additions to 2030 Cr decrease the rate. All the alloys produce a virtually pure CoO layer outside a ...: 32slovakia: 32slovakia
